29933gmol

29933gmol refers to a polymer characterized by an average molecular weight of approximately 29,933 g mol⁻¹ (≈29.9 kDa). It is commonly a linear poly(ethylene glycol) derivative, synthesized through controlled ring‑opening polymerization of diethylene glycol monomers followed by end‑group functionalization with a diacid or diamine linker. The resulting macromolecule exhibits exceptional water solubility and biocompatibility, making it a popular scaffold in biomedical formulations.

The polymer’s physical properties include a glass transition temperature near 25 °C and a melting point well above 80 °C. Its mechanical integrity allows it to serve as a hydrogel matrix when cross‑linked with biodegradable cross‑linkers such as poly(ethylene glycol) diacrylate. In solution, 29933gmol can stabilize colloidal nanoparticles, preventing aggregation, and can act as a stealth coating to prolong systemic circulation in drug delivery applications.

In pharmaceutical research, this polymer is often conjugated to therapeutic agents, proteins, or imaging probes. The high ligand‑loading capacity (up to 10 mol% of functional groups) enables multivalent interactions with target receptors, thereby enhancing cellular uptake and biodistribution. Studies have demonstrated its use as a carrier for small‑molecule drugs, RNA interference agents, and cancer‑specific peptides, where the polymer’s size and surface chemistry improve bioavailability and reduce off‑target effects.

Manufacturers produce 29933gmol under various catalog identifiers (e.g., “PEG‑30 kDa” or “PEG‑29.9 kDa”). Batch‑to‑batch reproducibility is achieved through size‑exclusion chromatography and nuclear magnetic resonance characterization. Researchers routinely reference the polymer’s polydispersity index (typically 1.05–1.15) and verify functional group incorporation via mass spectrometry.

Overall, 29933gmol is a versatile macromolecular platform that supports a range of therapeutic and diagnostic innovations, with ongoing investigations exploring its application in gene therapy, vaccine delivery, and regenerative medicine.
